Level of evidence: B

Guselkumab treatment when compared to placebo, seems to increase the proportion of patients with moderate to severe plaque psoriasis to achieve a clinically meaningful improvement at 12 weeks of treatment.

It might be that there are not more adverse events in guselkumab treatment compared to placebo after 12 weeks of treatment but the level of evidence is low. The evidence is mainly based on 2 phase III RCT’s.
